Display device

Abstract

The disclosure relates to a display device, which includes a cover plate, a backlight unit, a display module disposed between the backlight unit and the cover plate, the display module including a first substrate close to the light exiting side of the backlight unit and a second substrate close to the cover plate, and a camera module arranged on the first substrate, the camera module including an infrared cut-off filter, wherein the first substrate extends horizontally beyond the second substrate and the backlight unit to form a mounting section for the camera module, and the infrared cut-off filter is arranged in the mounting section.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This patent application is a National Stage Entry of PCT / CN2019 / 085153 filed on Apr. 30, 2019, the disclosure of which is incorporated by reference herein in its entirety as part of the present application.BACKGROUND[0002]The present disclosure relates generally to the field of display technology, in particular to a display device with reduced thickness and effectively increased screen-to-body ratio.[0003]With the continuous development of electronic information technology, display devices, such as smart phones and tablet computers, are widely used and play an indispensable role in people's work and life.[0004]With the increasing popularity of display devices, ultra-narrow bezel, thinning and full screen of the display devices have become the mainstream trend. As the traditional camera exists as an independent unit in the device, it occupies a large space, which is not conducive to ultra-thinning and full screen. FIGS. 1A and 1B show conv...

AI Technical Summary

Benefits of technology

The present disclosure provides an improved camera module configuration that reduces the overall thickness of the display device and increases the screen-to-body ratio. By eliminating the need for infrared cut-off filtering film and the flexible printed circuit board dedicated to the sensor, the thickness of the camera module is reduced, and the display device becomes thinner. The effective utilization of the Z-direction space in the module structure allows for the camera placement in a single level area, while the X-direction space is utilized to increase the display ratio. The sensor and display module can share a main flexible printed circuit board and backlight unit flexible printed circuit board for their driving, further reducing the thickness of the display device. Overall, the present disclosure provides a thinner and more efficient camera module configuration for mobile phones and tablet computers.

Problems solved by technology

Because of the existence of the flexible printed circuit board, the (mobile phone) middle case and the bracket, the camera module, as an independent unit, has greatly hindered the trend of thinning and full screen of display devices such as mobile phones.
